description: >-
  Apollo ships a first-party hosted remote MCP server that exposes its 240M+ contact database, real-time
  enrichment engine, CRM records, sequences, tasks, conversations and analytics to AI clients. Streamable HTTP
  transport, OAuth 2.0 only — no API key, no local install. Also distributed as a built-in connector on ChatGPT,
  Claude, Perplexity, Replit and Cursor.

    Endpoint published verbatim by Apollo at https://docs.apollo.io/docs/apollo-mcp ("Endpoint |

    required | No | API key required | No"). Probed 2026-08-14: POST tools/list and POST initialize both
    return HTTP 401 {"error":"Unauthorized: Missing or invalid Authorization header"}, confirming a live
    server that gates the schema behind OAuth. The three /.well-known/ OAuth documents on the same host
    return 200 anonymously and are saved under well-known/.

  stdio_note: >-
    Apollo ships NO stdio/npx MCP package. apolloio/apollo-mcp-plugin is a Claude Code + Cowork plugin that
    wires the same remote endpoint; it is not a local server. Every documented client configuration
    (Claude Code, Codex, VS Code Copilot, Claude Desktop, Antigravity) registers the https URL.

  schema_note: >-
    Apollo documents 52 actions by name, description and credit cost, but does not publish inputSchema. The
    live tools/list is OAuth-gated (401 anonymous), so the real schemas require an authenticated
    introspection against a connected Apollo workspace. The names below are Apollo's own action labels,
    verbatim; parameter shapes are NOT recorded because they were not published.

constraints:
  - Destructive actions such as bulk delete are not supported.
  - Apollo prohibits AI model training with Apollo MCP integrations; model training must be off in the client.
  - Access is scoped to the authorizing Apollo user's own permissions.
  - >-
    Free Apollo accounts registered with a personal email address cannot use people/company search and
    enrichment actions, retrieve complete records, match contacts, or add people to prospects.
  - Apollo MCP uses separate rate limits from the REST API and does not return the x-rate-limit-* headers.
  - No additional cost to connect; the workspace's plan, permissions and credit balance still apply.
